sat in traffic this morning and cel came on, sounds the same drives them same, should i be worried? s:roll: :roll: s:roll:
I think everyones response to that would be to get it checked out anyway, to be one the safe side, think the AA and/or RAC can read the CEL for you, i'f your not too keen on going down to MR T.
only other alternative is to reset the ECU and pray it doesnt come back on again, but then you'll never know why it did in the first place.
Seans not far from you and has a code reader

yeh know what you mean anybody know roughly how much mr t charges as would like it to be checked out as there is obviously a problem.
cheers mark will pm him and ask the question
or do i just ring warranty direct and see if there service is as good as therre prices ?

thats a good idea, i'v been wondering that ! ! ! wether the warranty company pays for the diagnostics ? ? ?
question to be asked me thinks

And his hourly rate is pretty good too s:lol: :lol: s:lol: s:lol: :lol: s:lol: Only messing s:wink: :wink: s:wink:
only prob is there was two options when i signed up franchise dealer (main dealer) or network dealer, just one of there local garages and as you can imagine main dealer option was more expensive, will most "normal" garages have the code reader do you think?
Ed you have PM.
Thanks s:) :) s:)
right cel turned out to be a prob with o2 sensor but they have reset the ecu and cleared the error and hasnt come back on so they have told me to leave it as is and if light comes back on again o2 sensor may need replacing but seems fine at mo so im very s:lol: :lol: s:lol:
Had this myself a few days ago ( there seem to have been a few CEL incidents occurring recently ).
Was diagnosed by my dealer as a faulty O2 sensor, which they have now replaced.
Forgot to ask what the OBD code was, but the sensor in question was the one after the main cat.
Slightly OT, but word of praise for my local dealer ( Struans, Dundee ), I've always found their service to be courteous, honest and professional. I'd recommend them to anyone in the area.
Only downside of my visit is that they noticed my rears are barely legal ( 1.6 mm ) s:oops: :oops: s:oops: - need to order a set of T1-Rs.

I can second that praise. They spent the time to track down and silence all my interior squeaks and rattles. They also had no issues with TTE pipe re-alignment (even let me into the shop to give the final OK as they tightened everything up - ace!) They also replaced the bubbled rims on my previous 02 without question.
I think the best praise I can give is that they are honest. They don't sell alot of MR2's up here and they don't see many in for repairs. So when I was in for the rattle hunt, they said it would take a couple of days so they booked 3 days with a Yaris loaner.
my cel is back s:cry: :cry: s:cry:
Want to take me up on my offer again?
cheers sean, im going to reset the ecu at lunch time as i will be fitting my speedsource bushes then, if it goes out fair enough, if it comes back on thenm i know i have a prob and i may take you up on the offer thanks, think one of my o2 sensors is on the way out s:( :( s:(
just in case i do need a new o2 sensor im just looking through my warranty direct list of covered parts. It says anything not specifically mentioned is not covered. The nearest thing i can find is under the fuel system heading and could be either "sensors" or "airflow meter". Would i be able to argue it under these do you think or would they say the o2 sensors arent part of the fuel system?
booked in with warranty direct to be looked at tomorrow.
on another note i rang the garage who took my first reading (for the original error codes) they gave me the following...
P0172
P0175
I then looked these up in the articles section
System Too Rich (Bank 1)
System Too Rich (Bank 2).
Three questions really, they said that system was running too rich due to a faulty o2 sensor (originally), but if there was a faulty o2 sensor wouldnt this give a faulty o2 sensor error code?
Secondly if my car is running too rich is it ok to drive until tomorrow, and if its not the o2 sensors what other things could cause it to run rich?
cheers peeps s:) :) s:)
better too rich than too lean
in the short term should be ok to drive it.
since you are getting both banks too rich, this would indicate either both 02 sensors are faulty or there really is a problem.
what coudl cause you to run rich?
a) very very dirty airfilter (unlikely you'd be down on power)
b) MAF, have you cleaned it? could be faulty?
c) faulty injector/s unlikely as you'd need multiple faults to make both banks run rich
d) coked up 02 sensors? unlikely but you coldl try cleaning with some carb cleaner.
my money is on teh MAF
The other thing to note - if the O2 sensors are 'seeing' too much fuel in the exhaust and they are actually the faulty item then the ECU will have backed the fuelling off to it's minimum possible trim before reporting the too rich fault. This will leave the engine running much too lean which is a very bad thing s:( :( s:(
It is unlikely to be both O2's at the same time, so I would point the finger at the MAF - just ask Mark how rich the engine runs when the MAF doesnt know the correct amount of air going through it s:twisted: :twisted: s:twisted: (I'm still cleaning the soot of the front of my car s:!: :!: s:!: )
airfilter should be fine as had the full service around jun/july
maf i have cleaned it a few times with halfords electrical contact cleaner
tried cleaning the two manifold o2 sensors with same electrical contact cleaner, but when that evaporated they went back to the same "standard" whiteish colour
after reading what you have put mark i think it could well be faulty maf, as the others dont really sound plausable as would require multiple simultaneous faults, cheers s:D :D s:D
good points steve :-) :-) :-)

I dont think it is both o2 sensors as in your first point as the car has as much power as ever, sounds and feels fine. If it was running lean wouldnt it seem very underpowered?
on your second point although im obviously running rich doesnt appear smokey at all ? odd.
looks like could be new maf then anyway, how much is that going to cost warranty direct out of interest?
no ideaon teh cost of a MAF ed.
ref lacking power when running lean, it depends up to a point you will get more power when running ti lean.
however those cylinder temps are going to be very high.
well like said its unlikely to be both o2 sensors. everything just seems exactly the same as before the light came on, ah well its reported with warranty people now and booked in for first thing tomorrow morning, we shall see how we get on and i will let you know tomorrw :-) :-) :-) thanks once again everyone
Have you checked your oil level recently? One of the most common reasons for having both sensors reading "rich", besides all the reasons that Markiii has pointed out, is to be burning oil.
While it does not have a direct impact on performance, it is a particularly dengerous situation. As steve described, if both sensors read "rich" then the ECU tries to lean out the mixture, increasing the in-cylinder temperatures, potentially burning more oil.
I'm sorry if I seem a scarecrow, but it is always better safe than sorry.
i welcome all comments cheers carlos, never burnt much oil even before the precat gutting and now im gutted so to speak and i do check the oil quite often, so dont think it will be that. is looking increasingly like maf s:roll: :roll: s:roll: see what the garage says tomorrow s:) :) s:)
i know i keep saying it but this site is awesome, thanks to you lot s:D :D s:D

The 'soot' incident occured whilst trouble-shooting mark's Hass install - on it's first run after debugging the electrical gremlins the IC-Turbo hose got dislodged with the result that the ECU thought there was more air going in to the engine than there really was so it opened the injectors as much as possible. As there was no cat to deal with the unburnt fuel, it was ejected out of the back in a big black cloud s:shock: :shock: s:shock:
If your car is running rich enough to produce black smoke even with the main cat still in place then the cat is probably toast as well s:( :( s:(

nope no smoke so hopefully main cat is ok s8) 8) s8)
bloody warranty companies!! autocentre has just phoned me and says all sensors have checked out ok and they think it may be the maf as they have seen something similar once before. but as its not a definate fix, warranty direct aint paying for it and they now want to charge mr 50 for the check and 100 for the new maf!!!!!
spoke to them again and what there saying is the maf and all other sensors have tested out ok, but they will only pay if it will definately fix it, and there not sure that this will. So im going to swap mafs with my mate paul and then see who gets the error light come up on the dash then we will know for definate whether the prob is maf or something else. at least i know everything has checked ok and my car should be fine :-) :-) :-)
another update.
swapped mafs with paul and mine drove perfectly and his was a bit of a dog so maf is definately dead.
booked with warranty direct to be replaced tomorrow all costs covered except £25 excess so cant be bad £200 policy has saved me £125 already s:) :) s:)
Quadruple posting?! s:shock: :shock: s:shock: Tut tut Ed, you should know better... s:wink: :wink: s:wink:
Here's hoping that it is just the MAF matey, and that you get it sorted tomorrow. After all, summer is just around the corner...! s:lol: :lol: s:lol:

what can i say no one was talkin to me s:cry: :cry: s:cry:
yep hopefully it is just that, but car reved much easier and picked up nice and quick with his maf, now i got mine back its real slow to pick up like lack of fuel for a second...then it goes! after everything thats been said here and what the garage have said and the maf swap test im 99% sure all will be ok
and i know its Off topic but it is my topic hows the turbs runnin now, hehe s:) :) s:)
Great, but shite.
Pulls like Jordan (scared the hell out of a Scooby earlier this evening! s:lol: :lol: s:lol: ), but the flashing 'no cylinder 2 spark' light on the e-Manage has gone and is replaced by a red light flashing constantly really quickly. Going from the e-Manage support forums, it looks like there's some proper dodgy wiring connections going on somewhere, so I'll get that sorted next year. No CELs at all though... s:? :? s:?
Not tooooo bad then. Cool, keep looking at thors pages and dreaming, i do that is... s:) :) s:)
